Oxygen sensors
Introduction
An on-off type oxygen sensor (in normal operating conditions, the voltage
generated by the sensors switches between a
value close to 1v and a value close to 0v) is mounted on each of the exhaust
manifold of the diavel.
Each oxygen sensor has its own internal heater, which recei ...
Throttle valve position sensor
Introduction
The throttle valve position sensor (tps) of the diavel is mounted on the
throttle body.
The sensor is integrated into the throttle valve actuator motor, which
turns the spindle of the vertical cylinder throttle
valve directly.
The sensor sends information to the engine con ...
